Answer:

1.983(10⁴)

Step-by-step explanation:

Since we need to have ones and decimals as proper scientific notation, we have 1.983. Since we need the value of 19830, we need to move the decimal place 4 places to the right, so our exponent is 4.

Answer:

1.983 * 10 ^4

Step-by-step explanation:

19,830

Move the decimal so there is only 1 digit before the decimal

We move it 4 places to the left

1.9830

The exponent is the number of places moved, since it was moved to the left the exponent is positive

1.983 * 10 ^4

Can y’all help me plss

In a parallelogram,

⇒the angles adjacent to each other

⇒ are of the same measure

⇒so

∠A = ∠C

∠B = ∠D

Let's solve:

∠A = ∠C

$7z +5 = 8z - 10\\5+10=8z-7z\\8z-7z=5+10\\z = 15$

∠B = ∠D

$5w-30=3w+10\\5w-3w=30+10\\2w = 40\\w=20$

Let's check:

⇒ for all quadrilaterals like a parallelogram

⇒all the angle measures added up to 360, so:

$(7z+5)+(8z-10)+(5w-30)+(3w+10)=360\\(7(15)+5)+(8(15)-10)+(5(20)-30)+(3(20)+10)=360\\(105+5)+(120-10)+(100-30)+(60+10)=360\\110+110+70+70=360\\220+140=360\\360=360$
